POLISHING-WHEEL.

Specification of Letters Patent.

Patented April 30, 1907e Application filed February 10,1906. Serial No. 300,397.

To aZZ whom it may concern.-

Be it knownthat 1, JOHN B. FONTAINE, a citizen of the United States, residing at Marlboro, in the county of Middlesex and Com- Inonwealth of Massachusetts, have invented a new and useful Improvement in Polishing- Wheels, of which the following is a specification, accompanied by drawings forming a part of the same, in which- Figure 1 is a perspective view of a machine containing a polishing wheel embodying my invention. Fig. 2 is a central vertical sectional view of the polishing wheel with an inclosed heating shell shown partially in section. Fig. 3 is a section on line 33, Fig. 2.

Similar reference letters and figures refer to similar parts in the different views.

My invention relates to a polishing wheel for polishing the heels of boots and shoes, and comprises an improved method of obtaining the necessary degree of heat on the rim of the polishing wheel to keep the waxed cloth at the proper temperature to accomplish the olishing, and also comprises means for applylng the wax to the cloth in a melted state, and it consists of the construction and arrangement of parts as hereinafter described and pointed out in the annexed claims.

Referring to the accompanying drawings 1 denotes the frame of the machine and 2 the shaft of a hollow polishing wheel 3, attached to the shaft by a set screw 4, having its rim 5 covered with waxed cloth secured thereto in the customary manner in wheels of this class. The polishing wheel is provided with a removable side 6 attached to the wheel by screws 7 having a hollow hub 8 and a cover 9.

The interior chamber of the polishing wheel is fitted with a heating shell 10 supported on the end of a rod 1 1 passing through the cover 9 and adjustably attached to a post 12. The shell 10 toward the bottom is slightly contracted from a circular form at a, a, to obviate the necessity of making a true fit between the shell and wheel, and the bottom itself is horizontal at Z), the plane of the bottom approximately corresponding with the lower edge of the opening in the hol low hub 8. The upper surface 0 of the periphery of the shell 10 is concentric with the inner surface of the interior chamber of the polishing wheel and is arranged to contact therewith, both surfaces being polished to increase the accuracy of the contact. The face (Z of the shell 10 is also polished to contact closely with the polished side a of the polishing wheel 3. A steam pipe 13 enters the upper portion of the shell 10 through the hollow hub 8 and cover S), and an exhaust pipe 1 1 communicates with the lower portion of the shell. The steam pipe 13 and exhaust lt are likewise connected with the space inclosed between the double walls of a wax trough 15, in which runs a disk wheel 16 carried on a shaft '17 and driven by a belt 18 from the shaft 2. The wheel 16 is provided with one or more radially projecting spurs or teeth 19, arranged to contact with the cloth covering the periphery of the polishing wheel and impart melted. wax thereto.

The operation of my improved polishing wheel is as follows: The shell 10is inserted in the interior chamber of the polishing wheel 3 by removal of the side 6, and it is held from rotation and in contact with the interior surface of the polishing wheel 3 by means of the rod 11 while the polishing wheel revolves with the shaft 2. Steam is admitted through the pipe 13 thereby heating the shell 10, which heat is communicated to the polishing wheel 3. The exhaust steam passes out of the shell 10 through the pipe 14 and the water of condensation collecting on the horizontal bottom I) of the shell is also removed through the exhaust pipe 14. The exact shape of the shell. 10 is immaterial, but there must be sufficient contact between the shell and the polishing wheel to accomplish the communication of heat su'llicient to the wheel, and provision must also be made for the removal of the water of condensation. l/Vax is heated in the trough 15 by the admission of steam between its walls, and the melted wax is applied to the surface of thepolishing wheel by the lug 19 on the wheel 16.

\lVhat I claim as my invention and desire to secure by Letters Patent is 1. The combination with a rotatable polishing wheel, provided with an inclosed concentric chamber, of a removable side having a hub, a cover for said hub, a non rotatable shell held in said chamber, and inlet and outlet pipes passing through said cover and communicating with said shell.

2. The combination with a polishing wheel provided with a concentric chamber, of a removable annular side attached to said ICC wheel, a hub projecting from said annular side, a cover for said hub, a shell inclosed in said concentric chamber and in contact with the sides thereof, and inlet and outlet pipes communicating with said shell and passing through said cover.

3. The combination with a polishing wheel provided with a concentric chamber open at one side of said wheel, an annular cover detachably attached to said wheel to close its open side, means carried by said cover for the attachment of a polishing cloth, a. segmental steam shell inclosed in said chamber, and inlet and outlet pipes communicating with said shell.

4. The combination with a rotatable shaft, of a polishing wheel carried on one end of said shaft, and having a concentric chamber open on one side, a removable cover closing the open side of said wheel and forming an inclosed chamber, a shell held in said chamber, and inlet and outlet pipes communicating with said shell and passing through said cover. r

5. The combination with a rotatable shaft, of a polishing wheel having a concentric chamber and. held on one end of said shaft, said wheel having its side opposite said rotatable shaft open, a removable annular side attached to the open side of said wheel, a fixed shaft passing through the opening of said annular side, a shell carried on the end of said fixed shaft and inclosed in said concentric chamber, a cover supported on said fixed shaft and closing the opening in the removable annular side of the wheel, and inlet and outlet pipes for said shell.

6. The combination of a rotatable shaft, a fixed shaft in alinement therewith, a polishing wheel carried on one end of said rotatable shaft and having an inclosed concentric chamber, an annular opening around said fixed shaft communicating with said chamber, a stationary cover held on said fixed shaft closing said annular opening, a steam shell carried on the end of said fixed shaft and inclosed in said concentric chamber, and inlet and outlet pipes communicating with said shell and passing through said stationary cover.

7. The combination with a rotatable polishing Wheel having an inclosed concentric chamber provided with an annular opening communicating with one side of said chamber, of a segmental steam shell inclosed in said chamber having a horizontal bottom in alinement with the lower edge of said annular opening, and inlet and outlet pipes communicating with said shell.
